This popular shrub can spread beyond cultivated areas and into native habitats in many eastern and midwestern states. As it is very tolerant of deep shade, it can thrive in the interiors of forests. Since it is a rapid grower, it can out-compete native plants, often forming dense thickets.
Porcelain berry overtakes other vegetation and can shade out native shrubs and trees. It can form thick monocultures which reduce species diversity and wildlife habitat.
Lesser Celandine is considered highly invasive, and in many states, nurseries are prohibited selling the
plant. Its rapid growth early in the spring allows it to out-compete many native ephemerals. This has the
effect overtime of allowing this invasive to become the predominant in the landscape.
